Description

SHEATH BEAM STRIPPER AND PRODUCTION METHOD THEREOF
Technical Field
The present invention relates to a sheath beam stripper which discharges pumping light that cannot be absorbed by active fiber in high-power fiber laser systems, from fiber optic cable; and production method thereof.
Background of the Invention
In all fiber laser systems, a certain ratio of pumping light transferred from pumping diodes to active fiber by means of combinary (fiber optic beam combiner) cannot be absorbed by active atoms included in fiber core and it continues to proceed in the sheath region of the fiber. Absorption ratio of pumping light is directly related to geometry and additive ratios of active fiber. The fact that laser signal and non-absorbable pumping light exit leave the fiber laser outlet together reduces the quality of the laser beam and causes the optical elements or materials that will be integrated to the outlet part of the fiber laser to be damaged. A component of sheath beam stripper is required in order to get free from this effect.
The International patent document no. W02008088336, an application in the state of the art, discloses coating all or part of one or more surfaces of a shaped article with a covering material. The article of manufacture shaped or to be coated may be fiber optic cable. The shaped product can be coated by methods such as electrolysis coating, vapor deposition, vacuum evaporation, sputtering, or brushing spraying, overmolding, lamination and roller coating. The thermoplastic polymers used in coating have high temperature resistance, good electrical properties, and good hydrolytic stability like polysulfones, poly(ether sulfone)s and poly(phenylene ether sulfone)s.
Summary of the Invention
An objective of the present invention is to realize a sheath beam stripper which discharges pumping light that cannot be absorbed by active fiber in high-power fiber laser systems, from fiber optic cable; and production method thereof.
Another objective of the present invention is to realize a sheath beam stripper which can scatter light better than thin films, and production method thereof.
Another objective of the present invention is to realize a sheath beam stripper which is used as light stripper, and production method thereof.
